Tetrapentylammonium molybdates

Tetrapentylammonium molybdates. Kroenke, William J. (Goodrich, B. F., Co., USA). U.S. US 4410463 A 18 Oct 1983, 4 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07F011-00. NCL: 260429000R. APPLICATION: US 82-402481 28 Jul 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 49 Tetrapentylammonium molybdates having the formula [(CH3(CH2)4)4N]aMobOcHd [a, b, c = (2, 2, 7), (3, 5, 17), (2, 6, 19), (6, 7, 24), or (4, 8, 26); d = 0, 1] are useful as smoke retardants for PVC. Thus, a mixt. of 10.00 g tetrapentylammonium bromide [866-97-7], 2.60 g 37% HCl, and 200 mL water was treated with a soln. of 8.98 g (NH4)2Mo2O7 [27546-07-2] in 50 mL water. The mixt. was refluxed for 30 min and worked up to give a yellow product which was a mixt. of tetrapentylammonium hexamolybdate (I) [88814-96-4] and tetrapentylammonium a-octamolybdate (II) [88845-74-3]. A compn. contg. PVC [9002-86-2] 100.0, lubricant 2.0, Sn stabilizer 2.0, and I-II mixt. 2.0 parts was milled and pressed into sheets having 34.6 max. smoke d./g resin, vs. 60.8 for a control prepd. without the molybdate mixt.

Didodecyldimethylammonium molybdates

Didodecyldimethylammonium molybdates. Kroenke, William J. (Goodrich, B. F., Co., USA). U.S. US 4410462 A 18 Oct 1983, 4 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07F011-00. NCL: 260429000R. APPLICATION: US 82-402477 28 Jul 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 49 Didodecyldimethylammonium molybdates having the formula [[CH3(CH2)11]2Me2N]aMobOc [a, b, c = (2, 6, 19), (6, 7, 24), or (4, 8, 26)] are useful as smoke retardants for PVC. Thus, a soln. contg. 10.00 g didodecyldimethylammonium bromide [3282-73-3], 2.13 g 37% HCl, and 200 mL water was mixed with 7.35 g (NH4)2Mo2O7 [27546-07-2] in 50 mL water. The mixt. was refluxed for 30 min and worked up to give 13.87 g didodecyldimethylammonium b-octamolybdate (I) [88821-28-7]. Samples molded from a compn. contg. PVC [9002-86-2] 100.0, lubricant 2.0, Sn stabilizer 2.0, and I 5.0 parts had max. smoke d. 28.0/g, vs. 60.8/g for a control prepd. without I.
